Speaking to SiriusXM's Morning Mash Up about his love for California-based fast food chain In-N-Out, he shared, "I left my wife and child at home and I was straight out to In-N-Out burger. I'm just kidding."

So what's really going on here? A source confirms to E! News that the 23-year-old and Cole, 33, are not married. In fact, Liam calling the new mom his missus is a common slang term in the U.K. used when mentioning your S.O.

And while Liam is not officially off the market, he's loving life with his partner of more than a year, especially now that he's a doting dad to baby Bear Payne. The couple's first child together was born in March, and in his first sit-down addressing their super private relationships, Payne called the pop star his dream girl.

"This is the thing: In a non-cliché way, it's weird waking up every day and literally living out your dream...Obviously I have the most beautiful girlfriend in the world, and she's absolutely amazing," he gushed to U.K.'s Rollercoaster magazine. "She's been my dream girl since I was younger. She's so ace."

Liam added, "She is a wonderful, wonderful person, and it's amazing to have someone who can relate to so much of things—someone who's taken greater steps than me."
